Thus, after the two are completely bonded by the guide alignment, the guide structure can be completely accommodated in the front end of the support member 4, and the hollow space in the front end of the support member 4 can be fully utilized. It should be understood that the convex-concave configuration of both the first guide structure 21 and the second guide structure 41 may be interchanged as desired, such as the first guide structure 21 being a concave guide surface and the second guide structure 41 being a convex guide surface.
In the configuration shown in the figure, when the spout 2 is brought into abutting engagement with the support member 4 during the withdrawal and return of the spout 2, the convex guide surface 22 is fitted into the concave guide surface 42 provided on the end surface of the support member 4. Can utilize the eccentric rounding off curve of the direction radial direction of the outer profile of the protruding surface 22 of direction that goes out water portion 2, the eccentric rounding off curve of the radial direction of the concave surface 42 of the inner chamber direction of cooperation second guide structure 41, the protruding surface 22 of direction and the concave surface 42 of inner chamber direction are similar in shape, the size is close, parallel fit clearance has, when the protruding surface 22 of direction falls into the concave surface 42 of direction, if not when lining up, the protruding surface 22 of direction and the concave surface 42 of direction only have 2 unbalanced little contact points, can't reach equilibrium, the play water portion 2 that has the protruding surface 22 of direction at this moment will reset along the concave surface 42 inner chamber face autogiration direction of direction, force the protruding surface 22 of direction to fall into the interior chamber face completely, finally two curved surfaces reach parallelly.
According to the present understanding, the drawing type water outlet device provided by the embodiment of the present invention has the advantages that two surfaces of the guide can be directly formed through the mold, no other guide parts need to be assembled or formed again, and the automatic reset guide structure has the advantages of simple structure and low cost. And because there are no other assembly parts. Still have the advantage that stable in structure fault rate is low.
The round curve with at least one eccentric radial direction is eccentric to at least one radial direction, the eccentric is eccentric from the center of a circle to form a non-round shape so as to have the capability of direction selection, and the shape is a round closed curve so as to smoothly guide and slide. At least one rounded curve that is eccentric in the radial direction is for example of the so-called cam-shape, oval-shape.
